In the microcontroller era today, Arduino ... at its sensor input port. As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion ...

Get close enough to this raven and you’ll set off the PIR sensor, which triggers lighting ... This bird’s brain is an Arduino Nano, which is protected from the 12V supply with a boost converter.

Inclusion of a microcontroller, on the other hand, not only gives some design ... The code is an Arduino project for the Digispark Attiny85 to turn on a light source when the PIR sensor detects ...

The device collected dust in his room for some a while until he recently unearthed it, and noticed that a perfectly good PIR ... sensor’s signals, allowing him to easily wire it up to an Arduino.

You’ll see PIRPin defined as “2” and OutPin defined as “3”—these correspond to where you plugged the PIR sensor and power relay into the Arduino. With your fan unplugged, turn it on ...
